The Bullet has been a mainstay of Royal Enfield’s single-cylinder line up for decades and for 2026 it’s getting a 650cc twin-cylinder sibling that follows the tried-and-tested formula of offering lots of bike for minimal outlay, hot on the heels of the Interceptor, Continental GT Super Meteor, Shotgun, Classic and Bear. This indeed is Royal Enfield’s seventh model to use this engine configuration since 2018. The Bullet’s parallel twin engine is the same Euro5+ compliant unit that’s already fitted to a host of other models including the Super Meteor, Shotgun 650, Bear 650, Classic 650, Interceptor 650 and Continental GT, so it’s a known factor. The old-school, air-and-oil-cooled twin might be one of Royal Enfield’s newer additions, but it’s still a throwback in terms of tech, with a single overhead camshaft and a relatively long stroke design – the bore is 78mm, the stroke is 67.8mm – that’s not built with outright performance in mind. It’s A2 licence legal thanks to 46.4hp (34.6kW – just below the 35kW limit for the class), and hits its peak power at 7,250rpm. Max torque is 38.6 lb-ft and comes at 5,650rpm. The power goes through a six-speed box and a wet, multi-plate slipper clutch, with a chain final drive.
